Definitions
- the present invention relates to a method for converting thermal energy into mechanical work.
- the DE 32 32 497 A discloses a method and apparatus for converting thermal energy into mechanical work by supplying hot heat transfer medium to a first working space of a heat exchanger, heating a first amount of working medium in a second working space of the heat exchanger by the heat transfer medium, and connecting the second working space the heat exchanger with a pneumatic-hydraulic converter and the ejection of a hydraulic medium from the converter by the pressure of the working medium.
- the cylinder must be alternately heated and cooled, which takes corresponding time due to the available heat capacity. The performance of such a device is thus limited.
- the US 4,617,801 A shows a free-piston machine for the conversion of thermal energy into mechanical work.
- pneumatic-hydraulic transducers are used to transfer the pressure into the system.
- the device has a complex structure and a modest efficiency.
- Object of the present invention is to provide a method of the type described above in such a way that even under thermally unfavorable conditions, a high efficiency can be achieved, the apparatusive structure is minimized.
- the heat transfer medium which has been heated to 100 °, for example, by an internal combustion engine, is introduced into a first working space of a first heat exchanger.
- this first heat exchanger is a so-called bladder accumulator, which is a pressure vessel with two working spaces, which are separated by a flexible membrane.
- the first heat exchanger could also be designed as a cylinder having two working spaces separated by a piston, as long as the piston is designed so that a heat exchange is easily possible.
- the heat transfer medium is introduced in this first step so far in the first heat exchanger, that the first working space reaches about half of the total volume of the heat exchanger.
- a working medium which is present in the second working space of the first heat exchanger, is heated by the first heat transfer medium. It is the main part of the heating, since of course a certain warming already takes place during the supply of the heat transfer medium in the first working space. This main part of the heating is isochoric, since all the valves that allow access to the second working space are closed. Due to the temperature increase in the second working space, the pressure of the working medium increases accordingly.
- the second working space of the first heat exchanger is connected to the second working space of a second heat exchanger, so that the working medium flows over into this working space.
- the overflowed working medium cools down, and at the same time, as a result of the volume increase of the second working space of the second heat exchanger, heat transfer medium is displaced from the first working space.
- This process continues until about the first and the second working space of the second heat exchanger have an approximately equal volume. After closing the corresponding valves, in turn, isochore heating of the working medium in the second working space of the second heat exchanger, which is the fourth step.
- two, three or more heat exchangers are connected in series.
- a connection of the second working space of the second heat exchanger to a pneumatic-hydraulic converter which is preferably also designed as a bladder accumulator, now takes place in the fifth step. Due to the expanding working medium, the hydraulic medium is expelled at high pressure from the pneumatic-hydraulic converter, for example, to drive a work machine.
- steps three and four of the method are repeated as often.
- very high pressures of 200 bar to 300 bar can be achieved, so that very high efficiencies can be achieved.
- the efficiency can be increased in particular by the fact that after establishing the pressure equalization between the second working space of the preceding heat exchanger and the second working space of the subsequent heat exchanger further heat transfer medium is pressed into the previous heat exchanger to transfer working fluid from the second working space of the first heat exchanger and the previous heat exchanger in a second working space of another subsequent heat exchanger.
- the use of mechanical work is required to completely expel the working medium after the overflow from the second working space of the respective heat exchanger.
- this additional expense is offset by a higher energy yield, which increases the efficiency accordingly. It is particularly advantageous to completely empty the second working spaces of the heat exchangers.
- the first working spaces are completely emptied. This is done by introducing working fluid into the second working chambers of the respective heat exchanger, which can be done virtually without pressure.
- the working medium is compressible, with both the possibility exists to use a gaseous working medium, as well as to provide a liquid / gas phase mixture. It is particularly preferred if the working medium has a boiling point at ambient pressure which is between -60 ° C and -20 ° C.
- a particularly favorable embodiment variant of the method according to the invention provides that several cycle processes are carried out at regular intervals with a time offset. This means that, similar to a multi-cylinder internal combustion engine cyclic fluctuations can be compensated and in particular in the hydraulic system equalization of the pressure can be brought about.
- the energy fed into the hydraulic system can be used in various ways.
- a feed can be made in a hydraulic network to drive hydraulic machines.
- the generation of electric power via a generator is provided which is driven by a hydraulic working machine.
- the present invention also relates to a device for converting thermal energy into mechanical work, having at least two heat exchangers, each having a first and a second working space, wherein the first working space is connected to a source of hot heat transfer medium.
- this device is characterized in that the heat exchangers have second working spaces which can be connected to one another and to a source of a working medium and that the second working space of a heat exchanger can be connected to a pneumatic-hydraulic converter.
- the heat exchangers each have a smaller volume starting from the first heat exchanger. As a result, a particularly high overall efficiency can be achieved.
- Fig. 1 shows a circuit diagram of an embodiment of the present invention.
- the device according to the invention consists of three heat exchangers 1a, 1b, 1c, which are designed as bladder accumulators.
- Each heat exchanger 1a, 1b, 1c has a first working space 2a, 2b, 2c and a second working space 3a, 3b, 3c, which are separated from each other by a flexible membrane 4. Due to the flexibility and the thin-walledness of the membrane 4 it is ensured that in the first and second working space 2a, 2b, 2c; 3a, 3b, 3c of each heat exchanger 1a, 1b, 1c always the same pressure and at least after a short transition phase also substantially the same temperature prevail.
- the first working spaces 2a, 2b, 2c of the heat exchangers 1a, 1b, 1c are connected via valves 5 to a line 6, in which the heat transfer medium circulates.
- This heat transfer medium is circulated by a pump 7 and comes from an internal combustion engine 9, which uses the heat transfer medium, for example, as cooling water.
- a high-pressure pump may be provided to completely empty the second working chambers 3a, 3b, 3c of each heat exchanger 1a, 1b, 1c by injecting heat transfer medium into the first working chambers 2a, 2b, 2c of the heat exchangers 1a, 1b, 1c ,
- a buffer 8 is used to set the respective desired pressure.
- the second working spaces 3a, 3b, 3c of the heat exchangers 1a, 1b, 1c are connected via valves 10 to a line 11 for a working medium, more valves 12 being provided between the individual heat exchangers 1a, 1b, 1c.
- the valves 10 are formed as multi-way valves.
- the working medium is conveyed via a pump 14 from a reservoir 15.
- Via further valves 13 and 16 is connected to the line 11, a pneumatic-hydraulic converter 17 in connection, which has a hydraulic chamber 18 and a working space 19, which are also separated by a flexible membrane 4 from each other.
- the line 11 for the working medium is continued after the branch to the pneumatic-hydraulic converter 17 via a first radiator 20 and a second radiator 21, between which a throttle 22 is arranged. Following the second cooler 21, the working medium is led away to the reservoir 15.
- the hydraulic circuit which starts from the pneumatic-hydraulic converter 17, consists of a first check valve 23, behind which a hydraulic motor 24 is provided, which is connected to a generator 25 for generating electrical power. Downstream of the hydraulic motor 24, the hydraulic medium is supplied to a reservoir 26, from which it is returned to the pneumatic-hydraulic converter 17 via a second check valve 27.
- the system is designed for a maximum pressure of 250 bar and the first heat exchanger 1a has a total volume of 200 liters.
- the second heat exchanger 1b has a total volume of 160 liters and the third heat exchanger 1c has a total volume of 120 liters.
- the pneumatic-hydraulic converter 17 has a volume of 80 liters.
- Fig. 1 shown devices arranged side by side in parallel and operated offset in time to each other, as is the case for example in a five-cylinder internal combustion engine.
- the first working spaces 2a, 2b, 2c have a minimum volume, that is, the membranes 4 are practically completely located on the side of the heat transfer medium and the second working spaces 3a, 3b, 3c practically the entire inner volume of the heat exchangers 1a, 1b, 1c make up and filled with working medium.
- the working medium in the first heat exchanger 1a essentially has ambient temperature and the pressure corresponds to a pre-pressure of, for example, 5 bar, which is maintained as the minimum pressure in the system.
- the valve 5 belonging to the first heat exchanger 1 a is opened, and hot heat transfer medium having a temperature of, for example, 100 ° C. is allowed to flow into the first working space 2 a.
- the supply is terminated as soon as the membrane 4 is in a middle position, that is to say that the first and the second working space 2a, 3a have approximately the same volume.
- the first valve 10 associated with the first heat exchanger 1a the excess working fluid is returned to the reservoir 15.
- the valves 5 and 10 are closed, so that the working fluid in the second working space 3 a isochorically heated by the hot heat transfer medium in the first working space 2 a.
- the working medium in the second working space 3a After preparation of the temperature compensation after a few seconds, the working medium in the second working space 3a at a temperature of 80 ° C and a pressure of 80 bar before.
- the valves 10 and 12 are opened between the first heat exchanger 1a and the second heat exchanger 1b, so that the working medium from the second working space 3a of the first heat exchanger 1a can flow into the second working space 3b of the second heat exchanger 1b.
- heat transfer medium is returned to the line 6 until about the middle position of the membrane 4 is reached.
- all the valves 5, 10, 12 are closed and again an isochronous heating of the working medium takes place in the second working space 3b of the second heat exchanger 1b.
- the working medium Before the heating, the working medium has been cooled by the overflow to a temperature of 50 ° C and the pressure has dropped to 60 bar. After isochoric heating, the pressure is 120 ° C and the temperature is 85 ° C.
